Oracle products and components are affected by multiple vulnerabilities. The impacts of these vulnerabilities include remote execution of arbitrary code, information disclosure, and denial of service.


Oracle has released Critical Patch Update - April 2006. This update addresses more than thirty vulnerabilities in different Oracle products and components.

The Critical Patch Update provides information about affected components, access and authorization required, and the impact of the vulnerabilities on data confidentiality, integrity, and availability. MetaLink customers should refer to MetaLink Note 293956.1 (login required) for more information on terms used in the Critical Patch Update.

According to Oracle, none of the vulnerabilities corrected in the Oracle Critical Patch Update affect Oracle Database Client-only installations.

The PL/SQL Gateway vulnerability identified as PLSQL01 in the Oracle Critical Patch Update corresponds to US-CERT Vulnerability Note VU#169164, which includes further details including workarounds.

In most cases, Oracle does not associate Vuln# identifiers (e.g., DB01) with other available information. As more details about vulnerabilities and remediation strategies becomes available, we will update the individual vulnerability notes.


The impact of these vulnerabilities varies depending on the product, component, and configuration of the system. Potential consequences include the execution of arbitrary code or commands, information disclosure, and denial of service. Vulnerable components may be available to unauthenticated, remote attackers. An attacker who compromises an Oracle database may be able to gain access to sensitive information.


Apply a patch

Apply the appropriate patches or upgrade as specified in the Oracle Critical Patch Update - April 2006. Note that this Critical Patch Update only lists newly corrected issues. Updates to patches for previously known issues are not listed.

As noted in the update, some patches are cumulative, others are not:

The Oracle Database, Oracle Application Server, Oracle Enterprise Manager Grid Control, Oracle Collaboration Suite, JD Edwards EnterpriseOne and OneWorld Tools, and PeopleSoft Enterprise Portal Applications patches in the Updates are cumulative; each successive Critical Patch Update contains the fixes from the previous Critical Patch Updates.

Oracle E-Business Suite and Applications patches are not cumulative, so E-Business Suite and Applications customers should refer to previous Critical Patch Updates to identify previous fixes they wish to apply.

Patches for some platforms and components were not available when the Critical Patch Update was published on April 18, 2006. Please see MetaLink Note 360465.1 (login required) for more information.

Known issues with Oracle patches are documented in the pre-installation notes and patch readme files. Please consult these documents specific to your system before applying patches.
